Quaternion Based Pose Detection Algorithm for Skiers

While targeting the issue of the lack of data support during the performance evaluation of skiers, an algorithm of attitude calculation required in the training of professional ski jumpers has been proposed. Considering the characteristics of the ski jumping, this algorithm calculates the attitude angle based on the quaternion and makes use of the Mahony algorithm for the error correction, realizing the goal of catching the attitudes during the ski jumping process with multidimensional parameters. The results of the MATLAB simulation experiment showed that this algorithm can effectively provide sensing of the attitudes of ski jumpers and the data processing method is simple and neat. It is concluded that it can provide valid reference data for the study on the training of skiers and the later research on intelligent protective devices.
